I have a spare Series 3 TiVo (model TCD652160) that is not being used. It works fine, but has no subscription to it & just sitting in a closet. I might be getting a broken TCD658000 from a friend. They claim (& think) the hard drive is the issue.

I will pull the hard drive and run the WD extended test on it to see if it is truly the hard drive. If it's not the hard drive and rather the power supply, can I simply swap these two power supplies? I realize the Series 3 (OLED) can't be used in either one of these, but was wondering if the TCD658000 & TCD652160 use the same power supply & are interchangeable since they look pretty much identical.

Now, if it is actually the hard drive that is the issue, can the 160GB hard drive from the TCD652160 be used in a the TCD658000?

The power supplies are interchangeable.
The 658 needs a larger hard drive . The 652 (or the Tivo HD as it's often called) has a smaller 160 gb hard drive and the software image is different and not directly compatible.

I was hoping the power supplies are interchageable and glad to hear that at least. Since I have installed an image for a Series 3 (OLED) myself, I had a feeling that the hard drives weren't really interchangeable though. Since I have a 658 image and a spare 1.5TB WD drive, I will try using this instead of the 160GB drive I have in my 652. I am also assuming the 658 can only go as high as 2TB too (if I ever decide to upgrade in the future)?

I believe that a 2TB drive is the limit for the 658 as well as the 652.

But then I thought the S3 was a 648250.

The 658 model is the tivo HD XL and the power supplies between the HD and HD XL are interchangeable. You are correct that the S3 OLED is the 648 model number.

Yea, from the way I understand it, there are two TiVo HD models (TCD652160 & TCD658000) that have interchangeable power supplies & the Series 3 OLED model (TCD648250B) that has its own unique power supply.

The 648 power supply has an extra wire to supply some oddball voltage for the OLED display, and until I investigate further, I don't recommend using a 648 supply anywhere except in a 648, or using anything in a 648 except a 648 supply.

If you've got the temporarily spare hardware to do it with, I'd be curious as to what happens when you try to boot a 658 with a drive smaller than 1TB with the 652 image on it, and I mean a drive other than one that actually came out of a 652 and might need to go back into one some day.

As I mentioned in the other thread where you asked about reviving the 658, the HD machines, at least the non-XL versions, used two different power supply models by two different manufacturers, and they are interchangeable, so if both your 652 power supplies are the same and the 658 is different, don't panic.
